NUTEC NC-50 / NC-51

About NC-50

Based on NC-41 (10W-50), this engine oil maintains NC-41’s performance while achieving a more affordable price through careful reformulation of the base oil.
The ester components and high-performance additives for lubricity, heat resistance, and high-temperature stability are blended at the same ratio as NC-41.
It fully addresses the extreme pressure and impact resistance requirements of four-stroke motorcycle transmission gears, so it can also be used as a viscosity variation of NC-20 (10W-40).
This is the ideal oil for circuit racing and high-speed riding in turbocharged vehicles, large-displacement bikes, and four-stroke large-displacement motorcycles.

About NC-51

Based on NC-40 (5W-30), this high-performance oil maintains the main components while achieving lower viscosity to fully cover circuit racing, high-speed riding, and street use for naturally aspirated engines.
The ester components and high-performance additives for lubricity, heat resistance, and high-temperature stability are blended at the same ratio as NC-40.

About NUTEC

NUTEC oil is a high-performance oil developed through original thinking and advanced refining technology, delivering high output, fuel efficiency, and low emissions.

  • Improved engine output / Reduces friction and improves combustion efficiency to enhance output.
  • Reduced fuel consumption / Improves overall efficiency through enhanced engine combustion efficiency to reduce fuel consumption.
  • Reduced noise level / Suppresses engine and exhaust noise.
  • Clean exhaust gas / Reduces CO, HC, and NOx.
  • Cleaner diesel smoke / Reduces black smoke emissions in exhaust gas.

Effects and features

  • A fully synthetic engine oil with ester as the main component.
  • The coefficient of friction matches Teflon performance, and heat resistance is maintained at an even higher level.
  • Oil created through ultra-fine molecular bonding forms an extremely thin yet strong oil film that protects friction and sliding surfaces such as cylinder piston rings, bearings, and valve lifters, delivering remarkable effects in reducing friction and improving sealing performance.
  • Improved sealing performance minimizes oil burning and oil sludge, suppresses sludge formation and blowby gas in the combustion chamber, raising compression pressure and improving combustion and fuel efficiency.
  • The ultra-fine components are extremely stable with excellent heat and pressure resistance, withstanding combustion temperature and pressure inside the cylinder. The ultra-thin oil film reduces friction, suppresses engine heat generation, and enhances thermal conductivity to control oil temperature rise. This makes it effective for air-cooled and diesel engines, delivering improved output and cleaner exhaust gas.
  • Ultra-fine components produce less oil contamination, extending the service life of oil filters and oil seals.
  • Using lubricant components from space shuttles and military applications, it excels in durability performance including high-temperature stability, oxidation stability, extreme pressure performance, and oil film retention.
